Thanks for the input everyone. I'm still waiting for an important part of my costume before proceeding with getting more leather.
Ssantoss - I've bought 8 snow white sheepskin hides so far, they were all 4-6 sq ft. The guy I bought them from is sold out right now and has been for months. I still need two or three hides to finish the costume. Note - I'm 5'7 so the amount of hides you need may vary.
